Abstract

A light diffuser for simultaneous photodynamic therapy and hyperthermic treatment in the oesophagus has an arrangement (14 to 18) which disperses radially the light (10) fed in by way of an optical fiber (6) and has a tube (12) filled with silicone to which are added concentrations, modulated in the axial direction, of quartz grains having a diameter of approximately 40 mu m which bring about a refraction having little dependence on the wavelength.
